CEMENTING-MACHINE.

Application filed July 21, 1911.

T all whom t1 n my concern:

Be it known that 1, JOHN B. HAD...WAY, a citizen of the United States, residing at Swampscot-t, in the county of Essex and State of lilassachusetts, have invented certain Improvements in Cementing-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for applyin adhesive material to stock and is herein illustrated in connection with a machine for applying cement to the skived margin of a piece of leather.

In the manufacture of boots and shoes it is customary to skive the margin of certain portions of the upper, to apply cement to said skived margin, and then to fold said margin, the purpose of this procedure being to improve the appearance of the finished edge.

It is desirable that the cement be applied evenly and the general object of this invention is to insure such application.

To this end, one feature of the invention consists in the provision with a cement applying member and a presser-member between which the stock is fed during the cementing operation of means for angularly adjusting one of said members; and in the illustrative machine the presser-member is made adjustable. With this construction and arrangement all points in the skived margin of the stock may be forced with equal pressure against the cement applying member and a uniform coating of cement thereby obtained whatever the angle of the skive.

This and other features of the invention including certain details of construction and combinations of parts will be described in connection with an illustrative machine and pointed out in the appended claims.

Referring now to the accompanying drawings :F igure 1 is a side elevation of a machine for applying cement to upper leather in which the present invention is embodied; and Fig. 2 is a front elevation of part of the machine, certain portions having been broken away to show more clearly the mounting of the presser-roll.

Referring now more particularly to Fig.

Specification of Letters Patent.

Serial No. 639,781.

1, a base 1 carries at its upper end a cement receptacle 3 and bearings 5 (see Fig. 2) in which is revolubly mounted the shaft 7 of the cement applying member, herein shown as a metal roll 9. A pulley 1O furnishes con venient means for applying power to the shaft 7. A valve (not shown) actuated by a lever 11, which is provided with a handle 13, as arranged to regulate the flow of cement from the receptacle 3 to the roll 9; and in order to insure that a coating of the proper thickness shall be taken on by the roll 9, a hood 15 partially encircles said roll, said hood being provided with a scraper or other suitable device for holding back the surplus cement.

The parts indicated above will not be described in detail, it being sufficient to state that when the shaft 7 is rotated and the valve which controls the flow of cement opened, the roll 9 is coated with cement which may be transferred to any article held against it.

Referring now more particularly to F ig. 2, a bracket 17 which extends horizontally from the base 1 is provided with a bore to receive a support, herein shown as a plunger 19, said bore being enlarged as shown to make room for a spring 21. This spring encircles the stem 23 of the plunger and bears with its lower end against a hollow adjusting nut 25. The stem 23 is threaded at its lower end and carries thereon a split adjusting nut 27 which may be clamped in adjusted position by means of a pinch screw 29. The plunger 19 is provided on each side with a pin 31 which extends into a slot 33 in the bracket 17 so that vertical movement only of the plunger is permitted.

The plunger or support 19 has formed in its upper end a curved guideway 85 having undercut sides; and slidably mounted in this guideway is a presser-roll carrier 37. This carrier is provided with ears 39 having alined bearings through which passes a bearing screw 41 upon the shank of which the presser-roll 43 is rotatably mounted. A slot is cut in one end of the bottom of the guideway 35, as best shown in Fig. 2, for the reception of a spring 45, said spring being held in place by means of a plate 47 which is fastened to the support by screws 49. Depending from the presser-roll carrier 37 is a lug 51 which is held between the spring 45 and an adjusting screw 53. Fast to the sides of the support are brackets 55 sustaining a table 57 on which is mounted an edge gage, herein'shown as comprising two parts 59 and 61 held in place by means of a screw 63. r

The stock is fed through the machine from left to right as viewed in Fig. 1 with the edge of the skived margin of the stock against the lower member 61 of the edge gage, said stock passing beneath the member 59. In order that the stock may be held firmly and presented properly to the cement applying member 9, whatever the angle of the skive, the are on which the guideway 35 is struck has its center in an axis which passes through the upper inner point 100 of the edge of the presser roll, said axis coinciding approximately with the lower edge of the skived portion of the stock. This point 100, therefore, remains stationary irrespective of the angular adjustment and is changed in location only when the support 19 is vertically adjusted. It will thus be clear that the presser roll may be angularly adjusted, that this angular adjustment does i not necessitate any vertical or lateral adjustment of the support, and that if a vertical adjustment of the said support is made to provide for a piece of stock of dilferent thickness, the angular adjustment may still be made as before.

In Fig. 2, a piece of stock is shown at A which appears at first glance to have its skived face in contact with the presser-roll 43. It should be understood, however, that this is not the case, but that the stockhas been distorted by the pressure of the roll 43 and that the skived face isin contact with the roll 9.

In the operation of the machine the nut 27 is adjusted in order to provide for the thickness of the stock and then the set screw 53 is turned in order to adjust the presserroll 43 to the angle of the skive. Power is then applied to the machine,'the valve which controls the flow of cement is opened, and the stock is fed through the machine after the manner shown in Fig. 2.

For convenience, the invention has been set forth in connection with a machine for applying cement to upper leather, but it mately with one edge of the skived portion 3 of the stock.

2. A machine for applying cement to the skived margin of a piece of stock having, in combination, a cement applying member and a presser member between which the stock is fed during the cementing operation, and means for angularly adjusting one of said members about an axis which coincides approximately with one edge of the skived portion of the stock.

3. A machine for applying cement to the skived margin of a piece of stock having, in combination, a cement applying roll and a presser roll between which the stock is fed, a carrier for said presser roll, a curved guideway in which said carrier is mounted, the curve of said guideway being concentric with an axis which coincides approximately with one edge of the skived portion of the stock, and means for adjusting said carrier in said guideway.

4. A machine for applying cement to the skived margin of a piece of stock having, in

combination, a cement applying roll and a' presser roll between which the stock is fed, a carrier for said presser roll, a yielding support for said carrier, said support being provided with a curved guideway in which said carrier is adjustably mounted, the curve of said guideway being concentric with an axis which coincides approximately with one edge of the skived portion of the stock, and means for adjusting said carrier in said guideway.'

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
